12. A manufacturing method of an electrochromic module is characterized by comprising the following steps:

providing a color-changing assembly; the color-changing assembly comprises a first substrate, a first conducting layer, a color-changing material layer, a second conducting layer and a second substrate which are sequentially stacked;

forming a protective layer on the surface of the second substrate, which is far away from the second conductive layer, and the side surfaces of the second substrate, the second conductive layer and the color-changing material layer;

and a protection plate is covered on one side of the protection layer, which deviates from the second substrate.

13. The method of claim 12, wherein the protective layer is formed by evaporation.
